From the story by Josh Rogin, here:
“This is a long game; it’s not a short game,” [Sam] Clovis said. He faulted neoconservatives who "think you can go out there and in three weeks after Iraq collapses you can create a constitutional democracy over there." ...
Sam Nunberg, who advised Trump on foreign policy early in the campaign before having a falling out with [Corey] Lewandowski, told me that Trump’s foreign policy was “Reagan-esque realpolitik,” a stance designed to be able to make policies based on circumstances without being burdened by ideology.
